Santa Ana National Wildlife Refuge
Santa Ana National Wildlife Refuge

United States, Texas


[edit] Overview

Along the banks of the lower Rio Grande is the Santa Ana National Wildlife Refuge, a 2,088 acre refuge established in 1943 for the protection of migratory birds. At an ecological crossroad, Santa Ana is strategically located where subtropical climate, gulf coast, great plains and Chihuahuan desert meet. Thousands of birds from the Central and Mississippi flyways funnel through the area on their way to and from Central and South America. This small patch of midvalley riparian woodland is also habitat for about one half of all butterfly species found in the United States.

The Refuge has been closed due to the flooding of the Rio Grande, but has recently re-opened for hiking/walking, nature tours, talks & programs! There are a few areas still closed due to damage from the flooding. Check the Friends of South Texas Refuges in External Links below.[1]

NB: A note from the Refuge Manager (Jan 28th, 2011): Please be aware that the entrance gate (parking lot gate) to Santa Ana National Wildlife refuge is being repaired and until it can be replaced a temporary gate has been installed. This gate will open at 7am daily and will close at 6:30pm. The gate will not automatically open so please make sure that you have left the parking lot by 6:30pm. We are working hard to get the automatic gate repaired. Thank you for your support and understanding.

This NWR is site LTC 059 on the Great Texas Coastal Birding Trail.

The 397 species of birds found on Santa Ana make it a birder's delight. Waterfowl, marsh birds and shorebirds can be seen on the lakes and wetlands of the refuge.

Migrating raptors that fly over the refuge in spring and fall include Osprey, Broad-winged Hawk, Northern Harrier and Peregrine Falcon. Santa Ana NWR's rarest raptors, the Hook-billed Kite and Gray Hawk, are seen occasionally on the refuge and attract birders from around the world.

Spring warblers are abundant, with over 35 species seen, including Golden-winged Warbler, Magnolia Warbler, Northern Parula and Tropical Parula, American Redstart, Palm Warbler and Yellow-breasted Chat.

[edit] Other Wildlife

Considered the jewel of the refuge system, this essential island of thorn forest habitat is host or home to nearly 400 different types of birds and a myriad of other species, including the Indigo snake and malachite butterfly. Bobcat, coyote, armadillo, long-tailed weasel and Mexican ground squirrel are present, too. The endangered ocelot and jaguarundi are also here, but difficult to see.

[edit] Site Information

[edit] History and Use

Before dams and control structures significantly reduced the flow of the Rio Grande, periodic floods cut shifting channels into the delta creating crescent-shaped oxbow lakes, referred to as resacas.

Santa Ana's management program mimics the historical flooding of the Rio Grande, maintaining the bottom land hardwood forest and providing crucial nesting and feeding habitat for birds, watering holes for animals, and homes for countless amphibians, reptiles, crustaceans and insects.

With over 95 percent of the original habitat in the lower Rio Grande delta cleared or altered, Santa Ana is a reminder of the semitropical thorn forest that once dominated the area.
